First off, I have a strong technical bias when it comes to photography (in case you couldn't tell). It looks like a case of camera shake due to generally low light levels (compounded by a shallow depth of field) gives this image an overall blurry look. Unfortunately, that's one of those things that's really hard to get around without some kind of stabilizer (tripod, lens stabilization) or way to bump up the shutter speed (lenses with bigger aperture openings). Flash can also help, but adding flash to the mix is it's own process.

The lighting worked out well. I like the soft lighting illuminating the face with a gentle transition to a darker zone along the cheek/hair. It looks like a candid shot, and the timing for capturing the pose was excellent; I really like the shape formed by the forearms and the interlacing of hands. The frame is nicely filled. The white balance/colour temperature looks very clean, perhaps even too clean and stark. Sometimes I like leaving indoor images a tiny bit reddish or orange to give them a warm feel.
